有していた。However, in the above-described configuration, in the method of attaching the communication pipe 4a of the suction muffler 4 and the cylinder head 7, the force for pushing down the suction muffler 4 in the direction of the insertion hole 7a of the cylinder head 7 is required. Since it is not hung, there is a dimensional gap between the communication pipe 4a and the mounting portion of the cylinder head 7. If the gap is large, rattling occurs between the communication pipe 4a and the insertion hole 7a, generating noise due to the vibration of the suction muffler 4, and removing the gap around the suction muffler from the gap between the communication pipe 4a and the insertion hole 7a. Refrigerant gas is sucked, and a suction noise is generated. Further, since a more inconvenient refrigerant gas is sucked, there is a problem that the volume efficiency is reduced. Therefore, usually, in order to make this gap as small as practically within the range of problems, high dimensional accuracy is required for both the communication pipe 4a and the mounting portion.
As a result, there is a problem that the mold life of the muffler is shortened, the number of processing steps is increased, and the muffler becomes expensive.
